Persistent memory
Agents remember durable decisions, patterns, fixes, preferences, and project context across sessions.
Self-hosted agent memory
Your AI agents finally share the same brain.
Give your coding tools the same local memory layer. Persistent context, reusable recall, and shared knowledge without another hosted dependency.

What it does
Durable project context without another hosted memory silo.
Agent Brain gives your local agents a shared memory store, semantic cache, and governance layer that outlives any single chat window.
C
Semantic cache
Similar prompts can reuse prior answers instead of burning tokens again.
N
Cross-agent context
Supported coding tools, scripts, and local integrations can all connect to the same shared memory.
L
Local model brain ops
Core memory operations run on hardware you control.
A
Memory governance
Audit, deduplicate, archive, restore, and consolidate memories so recall stays relevant as the corpus grows.
D
Desktop control plane
The desktop app manages setup, health, knowledge exploration, and monitoring.
How it works
Local services, one shared context layer.
1
Start the local stack
The desktop app or source setup starts the local services Agent Brain needs.
2
Connect your agents
Connect your agents through the supported local endpoints.
3
Store durable knowledge
Agents store durable project knowledge with structure and scope.
4
Recall what matters
Future sessions retrieve relevant context and share discoveries across tools.

MCP + REST adapters
Adapter layer
MCP clients use localhost:3100/mcp. REST and WebSocket clients use localhost:9090/api/v1.

FAQ
Common questions
Does Agent Brain send my code or memories to a cloud service?
No. Agent Brain is self-hosted. Core memory and recall operations run on your machine or infrastructure.
Which agents can use it?
Agent Brain works with supported coding tools, scripts, and local integrations through its public interfaces.
What does the semantic cache do?
It checks whether a similar query already has a useful answer. If the similarity score clears your threshold, agents can reuse the cached response instead of spending fresh tokens.
Do I need Docker?
Yes for the packaged local stack. Docker is required for the local services Agent Brain manages.
Is Pro checkout live?
Yes. Click 'Get Pro' on the pricing page to subscribe monthly ($19/mo) or annually ($190/yr). Community downloads are available now from the download page.
Can I use Community for commercial work?
No — Community is for personal and non-commercial use only. If you are using Agent Brain as part of paid work, a business, or a team, you need a Pro or Enterprise license.
